/*!
 * Public Tools — shared styles for /tools pages (Public Tools app).
 *
 * Plain CSS, no build step. Every class starts with pt- so nothing collides
 * with a theme's own .card/.btn styles, and interactive parts sit in
 * .not-prose so a theme's article typography (Tailwind "prose") leaves them
 * alone. Colours follow the theme where it says so:
 *
 *   --pt-accent   the theme's --bh-brand when it defines one, else blue-600
 *
 * A theme can restyle any of this by overriding the --pt-* variables.
